Description

The invention relates to the field of fractionation of small biological objects and can find application in breeding and laboratory practice.

The aim of the invention is to increase the efficiency in the operation of the device by ensuring the uniform and separate entry of small biological objects into the separation chamber, including pollen of flowering plants, and improving the convenience of servicing the device.

The drawing shows a device, General view.

The device includes a sealed loading hopper-feeder 1 with a cover 2, in which a nozzle 3 for introducing an energy carrier-air flow is mounted perpendicular to the bottom of the hopper, and an outlet nozzle 4 for discharging the air mixture. A vertical feed channel 5 is connected to the pipe 4. The lower end 6 of which is located in the upper part of the separation chamber 7. and the upper one is made with a reflective screen 8 in the form of blinds. A part of the exhaust pipe 9 connected to the vertical feed channel 5 is placed inside the latter and is made with a vertical section coaxial with the channel 5, and the output end of the pipe 4 in part 9 is facing upward to the reflective screen 8. The pipe 3 is connected to the discharge pump. Numbers 10–13 indicate the initial mixture, aerosol mixture, the core of the separating air flow, and the gas-object cloud, respectively.

The device operates as follows.

In the feed hopper-feeder 1 load the initial mixture of dispersed material 10 and close the lid 2. The pipe is connected to the air line from the discharge pump. Through the pipe 3 serves directional air perpendicular to the bottom of the hopper, which strikes the bulk mixture 10 of the dispersed material. Due to the fact that the speed of the air stream exceeds the speed of the particles of the dispersed material, an e-mixture 11 is formed in the inner space of the hopper-feeder 11. During the return movement of the air stream, it is turbulent. which leads to intensive mixing inside the mixture 11 and multiple rinsing of different speeds of each particle. Lumps and other aggregate formations disintegrate, the aerosol mixture acquires a uniform consistency Through the nozzle 4, the homogeneous aerosol mixture 11 enters the supply channel 5.

The air flow at the outlet 9 of the pipe 4 acquires a displacement component, the direction of which is opposite to the direction of gravitational forces. Therefore, the solid phase of the air mixture after entering the channel 5 rises along it up to a stop when interacting with the reflective screen 8. The fastest part is inhibited on the screen 8. In the channel 5, a gas object cloud 12 is formed in which individual particles are located at a sufficient distance from each other. This cloud is uniformly lowered along channel 5 into the separation chamber 7. The lower end 6 of channel 5 is located at a distance from the core 13 of the separating air stream. Therefore, the particles of the dispersed material, crossing the outlet, settle on the unperturbed separating air stream. .

When transporting charged particles, such as pollen from flowering plants, the transporting air duct is earthed.

To increase the uniformity of the gas-object cloud in the channel 5, the output 9 of the pipe 4 is placed coaxially with the exhaust channel 5.

The proposed device allows for uniform and separate injection of particles from an ensemble of small-sized biological objects, such as pollen of flowering plants, cereal flour, cocoa and coffee powders and others, into the separating air stream.
